This is only a small recreation project.

This little version of Johnny Five has working treads,

poseable head, neck, eyebrows, hands and laser gun.

Arms stand still where you leave them (trick, using Technic dark grey axle long 3).

He can follow lines with his sensor, placed between treads.

The 24z gears work also as wheels and receive torque from 8z gears, directly attached to motors.

Here's my other version of Johnny.

The robot is built only with

Lego Mindstorms RIS 1.5 kit.
